      abstract = {Field experiment was conducted in order to investigate the impact of different spacing on the growth and yield of Onion varieties in the year 2017 under rainfed and irrigation facilities at Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria. The treatments were four onion varieties (Local white, Texas grano, Local red and Red creolo) and six different spacing (0.3m by 0.2m, 0.3m by 0.3m, 0.3m by 0.4m, 0.3m by 0.5m, 0.3m by 0.6m, 0.3m by 0.7m). A recommended combined application of N and K fertilizers (60Kg N/ha x 120Kg K2O/ha) inform of Urea and Muriate of Potash (MOP)   (Atanda and Olaniyi, 2016) was applied at 2 weeks after transplanting. Texas grano variety recorded the highest values in all the parameters observed and this was obtained when onion was planted at the spacing of 30cm x 40cm. the study showed that at 30cmx 40cm spacing, Texas grano variety of onion could be produced successfully at Ogbomoso agro-ecological zone.},
